“I saw the results of Theo’s work when we were both at IBM working to derive the best UI principles to drive common user interface standards — before there were those, before users could reliably transfer their learning from one application to another. He codified the state of this early landscape in his book “The GUI-OOUI Wars” and contributed to clearer conventions, now in common across the graphical user interface paradigm. A great contribution and partner for any user interface work to come.”
